Plot

A giant insectoid-like deity dubbed Megalon appears in Japan and begins causing destruction, and it can only be stopped by a humanoid robot named Jet Jaguar.

History

After a young Japanese boy won a contest Toho had in mid-to-late 1972 for fans to come up with a new hero for them to use with his creation "Red Alone", the hero was renamed Jet Jaguar and set to appear in a film where he battled Megalon.

However, Toho figured Jet Jaguar would not be able to carry the film on his own, in screen appearance or marketing value (Possibly due to the popularity of Tokusatsu shows such as Ultraman Taro and Kamen Rider), so during pre-production, the project was shut down for several weeks, until screenwriter Shinichi Sekizawa was called in to rewrite the script to add Godzilla and Gigan. The resulting film, Godzilla vs. Megalon, paired Godzilla with Jet Jaguar against both Megalon and Gigan.
